I saw this when it aired: www.pbs.org... and in this documentary, researchers modeled the sort of impact that would have been
responsible for the extinction of large mammals in North America during that time... without leaving an impact crater.

there are too many occurences of a great flood happening when looking at the mythos of many cultures... And I don't buy the theory about this simply
being a story that spread from culture to culture, with the original story creator being affected by a great flood, either global or regional.

It seems as if many debunkers simply like to create a counter-story that in their mind seems more logical, when in fact their "theory" of what
really happened is often no better or credible than the original story. They demand proof where it is not even possible to obtain, yet never offer
proof to back theyre claims of it being untrue.

I say prove to me its NOT true!!

I understand that its good to ponder all things with a degree of skepticism, but some people seem to do it from an imagined position of great
intelligence, to serve their own ends, or simply to go against the grain. Either way, it usually says alot about their personality

More studies as I understand it are underway. As I have noted before it will take another 10-15 years of studies to get a handle on what happened. If
we're lucky a clear picture will emerge or if the picture is unclear and we have contradictory data we're be unlucky and the debate will go on
forever.....well at least until the event to find it is found.

Surovell's co-author Vance Holliday, an archaeologist at the University of Arizona in Tucson, and his colleagues have an article in press at Current
Anthropology that says the archaeological and geochronological records don't support a collapse of Clovis people at the time of the purported
impact.

The long-standing controversy regarding the late Pleistocene megafaunal extinctions in North America has been invigorated by a hypothesis
implicating a cosmic impact at the Ållerød-Younger Dryas boundary or YDB (≈12,900 ± 100 cal BP or 10,900 ± 100 14C years). Abrupt ecosystem
disruption caused by this event may have triggered the megafaunal extinctions, along with reductions in other animal populations, including humans.
The hypothesis remains controversial due to absence of shocked minerals, tektites, and impact craters. Here, we report the presence of
shock-synthesized hexagonal nanodiamonds (lonsdaleite) in YDB sediments dating to ≈12,950 ± 50 cal BP at Arlington Canyon, Santa Rosa Island,
California. Lonsdaleite is known on Earth only in meteorites and impact craters, and its presence strongly supports a cosmic impact event, further
strengthened by its co-occurrence with other nanometer-sized diamond polymorphs (n-diamonds and cubics). These shock-synthesized diamonds are also
associated with proxies indicating major biomass burning (charcoal, carbon spherules, and soot). This biomass burning at the Younger Dryas (YD) onset
is regional in extent, based on evidence from adjacent Santa Barbara Basin and coeval with broader continent-wide biomass burning. Biomass burning
also coincides with abrupt sediment mass wasting and ecological disruption and the last known occurrence of pygmy mammoths (Mammuthus exilis) on the
Channel Islands, correlating with broader animal extinctions throughout North America. The only previously known co-occurrence of nanodiamonds, soot,
and extinction is the Cretaceous-Tertiary (K/T) impact layer. These data are consistent with abrupt ecosystem change and megafaunal extinction
possibly triggered by a cosmic impact over North America at ≈12,900 ± 100 cal BP.

Its my position that the biblical flood is a composite of two events widely separated by time.
There is a dim memory of the flooding of the black sea basin some 9k? years ago and a much newer event some 4-1/2k years ago. This is the event
referenced in contemporary mesopotamian records.
There is burgoening evidence that there was yet another heavenly interloper in the affairs of man, the possible object that left burckle crater in
the indian ocean.

Like was mentioned inthat thread this was not the same flood referenced by the native americans.
But the floods referenced by the native americans were all the same flood either.
some were a memory of the devastating glacial lake break outs.
Some are of other large but local floods. And some are rememberences of thr great melt off caused by the younger dryas impact.

I've found this idea to be interesting even to the point of getting the book, alas it appears as my earlier skepticism was justified. However its a
good example of how egos can twist science and also how science, fortunately, slowly corrects itself.

Hey Bigfatfurrytexan, there was a great flood because of all the legends from people around the world (wiki flood myth). I came across that when I
first started to comment on this site a few years ago. Your comment about the water causing parts of a continent to move up or down is correct and I
didn't think about it until I googled the weight of 1 cubic meter of water. And it weighs 1,000 kilograms at 4 degrees celsius, and they say that
the temperature is important because density of water is effected by temperature and this temperature is water at it's densest. And at one thousand
kilograms that brings it to a little over 1 ton or 2,204.6 pounds. That isn't alot of water when you look at it, but it still weighs alot. And if
you add on that the same size of soil weighs 1.5 tons (give or take the moisture content).

So look at the last Ice Age, at where New York City is the ice was 1 mile thick and if you went further north into northern Canada, it was 2 miles
thick. This made the oceans 100 to 150 meters lower than today (but I think the oceans where closer to 250 to 400 meters lower, thats just to much
water that is trapped and also the effect of evaporation). So while the rest of the planet had areas and places that where very much dry lands until
the flood and/or archapeligos (like greece) and there was no seaway between Iran and Saudi Arabia at this time (You can find a good sea simulator
online that will allow you to lower and raise the sea level). Once the ice age started to warm up, the ice melted and water (specifically fresh water
started to flood into lands). But what caused much of the great flood (not all people had it happen at once some may have had water rising a decade
before etc., but most had it happen at one time), was from the ice dams. One happened in the upper plain states, what happens is that while the ice
melts, it not only start to flow into other areas but also into ice lakes that are on the surface of the ice sheets and also ice caverns inside the
ice sheets. So as the decades continue and centuries this water continues to build and build and build to the point that it may have a few oceans of
freash water sitting inside and on top of the super ice sheets. Then one day the ice dam/wall breaks and the water flows out and like any dam that
breaks the water quickly makes the open larger and larger until the massive amout of water is flowing out.

Heck there where some small ones and large ones and super big breakouts that may have happened more than once, but just imagine what I said about how
big those ice sheets where. Imagine 1/2 mile deep and 200 mile wide and 300 mile long (being very conservative it may have been alot bigger) of fresh
water is trapped behind a glacial wall that is breaking all at once. That water hitting an ocean or sea would cause a massive tsunami of water to
form from the introduction of the water pushing the sea forward. And then you will have to contend with the massive amount of weight that is put on
the land in front of the water that is filling up the basin and the weight leaving the cavity/land/ice shelf. One side would move up (don't know by
how much but it would) and the other side would go down. Just this alone could cause a ripple affect of earthquakes to happen (big ones) across the
planet and definitely cause some volcanoes to erupt from the compression and the decompression of the landmasses from the weight distribution.

It's hard for us to imagine a landmass to move up lets say 900 feet (I believe that the water lakes could have been as large as 2,000 miles both
direction and at least 1/2 mile deep all of a sudden just emptying into the ocean basin). Everyone has been schooled to believe that geological
activity takes eons and epochs to happen, but yet we see as an example from the 70's Mount Saint Helens blowing it's top off and half the volcano
sloughing off, quickly. And then these massive earthquakes cause other ice dams to break etc.. And I don't even take into account what would happen
to the planet with all the earthquakes and the massive amounts of water weight being sloshed back and forth into the ocean. Would it move the axis a
little or alot, after the Japan quake, it did effect the axis. I think their was an advanced planet spanning civilization during the Ice age, and
once this horrible effent happened it caused a new dark ages and survivors of this planet spanning civilization and what was left of the old world
tried to start the world back up via what was left and what they knew. These individuals may have been the helpers to the egyptians, and other
civilizations we know today (Olmecs, I think part of the secret is with the Olmecs of central and south america)

Most civilizations tend to be by a large body of water or river, and with the flooding happening most of this old world and cities are underwater
either off shore a few miles or underwater where land used to be and then the ocean came back to claim it. Like I said, once I figured out the weight
of water it hit me that this massive weight moving quickly could have easily caused earthquakes and filled areas quickly.

However, you really should read the link posted by Hanslune. That article doesn't effect our conversation on what water masses would do to
continental plates, but it does call into serious question the Younger Dryas Comet Theory.

I suspect this question will play out for another 10-15 years as research looks into the various aspects of this interesting phase in earth's
history. I would speculate that we will probably have a much more specific picture of about 2025, not definitely what happened but a framework to
flesh out with later research.

Not a real surprise -- as I think I mentioned, I talked this over with paleontologists and the evidence simply didn't match up with the bones. Nor
were the Clovis people suddenly extinct (as mentioned) -- they had to change their technology because hunting rabbits with a spearpoint the size of
your hand simply doesn't work. Too slow, too much damage.
